BEN WAS HURRYING to his next meeting when his boss stopped him in the hallway. "Ben, I'm heading up to the CEO's office for the budgeting meeting," he said. "Remember the system upgrade we talked about the other day? Could you give me a quick ballpark dollar figure that I can take to the boss just as an example? You won't be held to it, of course⋯" © 2012 ACM. Source

The article discusses how the speed of modern tools may decelerate development. As well as encouraging unplanned experimenting, faster development tools may paradoxically increase the time to complete programming tasks. They may do this by encouraging a large number of small iterations where the learning increment is minimal, instead of a small number of thoughtful iterations where people learn a lot. There are two forces at work here. One is the cost of experimenting, the other is the cost of all those iterations. As development tool speed increases, clearly it costs less and less to play with a problem. This is shown in the accompanying figure by the blue bars. When the turnaround time is very long, it is usually too expensive to consider experimenting unless Thinking has come to a complete dead end. Source
